WILLIAM A. JoNEs, or WEsTERLEIGH, NEW YORK, AssIGNoRl'ro THE :associessa WILcox COMPANY, or BAYONNE, NEW JERSEY, A coRPoRArrIoN'oF NEW JrasEYSTEAM'. BOILER AND CONDENSERFOR FAPOR FROM HIGH BOILING POINT LIG''IDS'Application sied Juiy 24,

This invention relates to a water tube steam i boiler in which thesteamis generated by the latent heat of condensation of the vapor of a highboiling point` liquid. The generating surfaces ofthe steam boiler areenclosed into a cylindrical shell into which the vapors are introducedand condensed.

An object ot theinvention is to provide a steam boiler wherein the steamgenerating surface or heat absorbing unitis heatedby a vapor from a highboiling point liquid, and in which, by reason ot' the differences intemperature betweenthe respect-ive parts, itis essent-iai to adequatelycare for the relative eX- pansioii and contraction of the compositearts.`

A further feature resides in the .particular construction of such aboiler as is mentioned iii the preceding paragraph, and wherein anexterior vapor receiving andcondensing shell houses the major portion ofa steam generating or heat absorbingunit for converting wateriiitosteam. and in which combination the 'parts are so arranged that theconnections to the heat absorbing unit may be entirely outside the vaporcontaining shell. thereby' eliniinating man v joints which wouldotherwise have to be iliade vapor-tight; and, also, so mounting the heatabsorbing unit with respect to the shell that it may expand and contractboth longitudinally and transversely1 wit-hout disarrangiiig the partsor producing vapor leaks.

The invention will be understood from the description in connection withthe accompanyingl drawings in which Fig. 1 is a vertical section throughan illustrative embodiment of the invention: Fig. 2 is a section partlvbroken away along the line 2-2 ot Fig. l; Fig, 3 is a section showingone of the details. Fig. 4 is a section along the line 1f-4t ot Fig. 1;and Fig. 5 is a similar section through a modification.

In the drawings reference character 1 indicates a easing or cylindricalshell that is provided with an inlet 2 at one end thereof for iiiercuiyvapors. An outlet 3 for condensed mercury is provided at the bottom.

The shell 1 is supported upon supports 4 near opposite ends and an upperdrum ex- 1928. Serial No. 294,957.

tends into the shell through one end and prajccts to some distanceoutside ot the shell. Si. similar lower drum 6 smaller than the drum 5is also provided and extends through the same end of the shell 1. Lvalved drain pipe 7 may be provided at the bottoni of the drinn 6outside of the shell 1. A- feed pipe E enters the end of the upper drum5 that extends outside ot the shell 1 and the feed pipe S extendssubstantially entirely through the drinn 5 and is supported upon crosssupports 9 at intervals. A. water level indicator 10 and satety valveconnections 11 are provided on the portion ot'v the drum 5 that extendsoutside of the shell. A dry pipe 12 supported by straps 13 is located inthe upper or steam space of the drum 5 and the outlet 14 from this drypipe extends through the upper surface of the extending end of the drum5.

Rows ot' bent tubes 15 connect the drums 5 and 6 on the inside otl thecasing 1 and the ends of these tubes enter both drums radially. Theupper drum 5 is supported upon cross supports 16 and the lower drum t3is supported from the drum 5 by means of the tubes `15 and is treeY tomove up and down when the tubes contract and expand. A flexible seal 17is provided between each drum 5 and 6 and the casing lwhere the drumspass through the casing. A portion of the seal 17 is shown in Fig. 3 onaii enlarged scale. The seals 1T are between the parts, namely, thedrums 5 and 6 which are in contact with the water or steam on one sideand vapor on the other side and the shell 1 which is in contactwithvapor only, so that difference in expansion between them may takeplace without causing leakage, that is, there are flexible seals betweenthe. steam. boiler and the vapor condenser shell. The mercury vaporshell 1 can in crease iii diameter in' starting up with cold water inthe drums 5 and 6 without causing leakage to take place due todiii'erenee in eE- pansion.

In the modification shown in Fig. 5, only one drum, namely, the steamand water drum 5 extends into the casing 1 and a portion of this drum onone. side of a vertical plane through the drinn is connected rows ofcurved tubes 15 to a similar portion or". the.

tit)

drum upon the other side of the plane, the ends of the tubes enteringthe drum on radial lines.

The operation is as follows: Feed Water is supplied through the feedpipe S, which may be provided with distributed openings in the drum 6,and the drum 5 is liept about half filled with water which also fillsthe tubes and the drum 6. Vapor-s ot a high boiling point liquid areintroduced into the casing 1 through the inlet 2 and condensing aroundthe tubes 15 andthe drums give up heat which generates steam from theWater in the drums 5 and 6 and tubes 15. The condensed vapor passes outthrough the outlet 3. The steam collects in the steam space of the upperdrum and passes out through the dry pipe 12 and outlet 14 to the placeof use.

I claim:
